摘要
A method for driving a liquid crystal display device capable of switching between a wide viewing angle and a narrow viewing angle. In a first viewing angle mode, a direct-current common voltage is applied to a common electrode and voltage signals are applied to a first bias electrode and a second bias electrode. In a second viewing angle mode, a direct-current common voltage is applied to the common electrode, a first alternating-current voltage is applied to the first bias electrode and a second alternating-current voltage is applied to the second bias electrode. In addition, in the second viewing angle mode, pixel units covered by each first electrode strip of the first bias electrode have alternating positive and negative polarities, and pixel units covered by each second electrode strip of the second bias electrode have alternating positive and negative polarities.
